GEORGE WASHINGTON SHOEMAKER, OF DALTON, PENNSYLVANIA.

RING-SPINNING MACHINE.

SPECIFICATION forming part of Letters Patent No. 357,864, dated Februaryl5, 1887.

Application filed April 3, 1886.

To all whom it may concern:

Be it known that I, GEORGE WASHINGTON SHOEMAKER, a citizen of the UnitedStates, residing at Dalton, in the county of Lackawanna and State ofPennsylvania, have invented certain new and useful'Improvements in Ring-Spiuning Machines, andl do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it apper-` tains to make and use the same,reference being had to the accompanying drawingsand to letters orfigures of reference marked thereon, which form a part of thisspecification.

Figure lis an elevation of one end of my improved ring-spinning machine,showing the drawing-rolls near the terminus of their downstroke. Fig. 2is a frontelevation of the machine,parts of one end of thesame beingbroken away. Fig. 3 is a section taken horizontally through Figs. l and2 in the plane indicated by dotted lines x m thereon, showing parts ofsome of the driving-hands removed. Figillis a detail of the fast cam andparts connected therewith. Fig. '5 is au enlarged perspective view ofpart of the main frame, its drawingrolls, endless racebelt,andpitnian-rod for the lower drawing-roll carriage.

My invention relates to certain novel irnprovements which are applicableto continuous drawing and ring-spinning machines for spinning wool,cotton, and other fibrous ma#` terials, which will be hereinafter morefully described'and pointed out.

Referring by letter t0 the accompanying drawings, A designates the mainframe, and

A the main driving-shaft suitably journaled thereon.

B designates a shaft driven from the main shaft A by means of a pinionspur wheel,

a, keyed on the latter,engaging with amaster spur-wheel, Z), on shaft B,as clearly shown in Figs. 1 and 2.

C is a shaft which receives rotation from the shaft B by the wheel b,engaging with a piuion, c, keyed on shaft C.

D is a spur-wheel which receives rotation from the large spur-wheel C2on the shaft C through the medium of a spur-wheel, e, keyed on the endof a shaft, e', of a drum, X2. This spur-wheel D transmits rotationdirectly to the feed-rolls E E by engaging with twin Serial No. 197,692.(No model.)

spurred pinions c3 c3, (shown clearly in Fig. 1,) and F are movablerolls which rest on the feedrolls E E.

An endless belt, B2, runs from a band-wheel, a, keyed on the nia-inshaft A', under a bandwheel, G, keyed on a shaft, G, thence overauidlerlpulley, J, and around a band-wheeh K,on a worm-shaft, K. The shaftG transmits rotation to a shaft, H, at right angles to it, by means'of abeveled pinion, H2, keyed on said shaft G, which pinion engages with alarge bevel spur-wheel, H", keyed on shaft H. On thisshaft H is abevel-pinion,2, which engages y with a similar pinion, 3, keyed cn thelower end of ashaft, I, which latter in turn transmits motion to ashaft, B", bearing a cam, B3, by means of the beveled pinions H3 and H4.

The cam B (shown clearly in Figs. 2and 3) receives its movements fromthe shaft K through the medium of the worm A* and worn1wheel L, andsaidband-wheel K receives rotation from the main driving-shaft by meansof the same belt,B27 which rotates the shaft G', as above described.

` M designates a rectilinear reciprocating carriage,which is guidedbetween pointsff-on an inclined way,N,and which bears the drawingrolls RR', on. top of which are other rolls, S. The journals of thedrawing-rolls R R bear race-pulleys R R, which impinge upwardly againstthe upper half of an endless race-belt, O, hereinafter referred to. Thedrawing-roll carriage M receives its traversing movements from themaster spur-wheel b by means of a pitman-rod, M, connected to the wheelby a wrist-pin, M2. (Shown in Fig. l.)

The endless race-belt O runs from the p ulley O on. the shaft C to apulley, l), which turns freely on a stud fixed to the side of the mainframe A. The frame h' receives an alternate forward and receding motion,and simultaneously therewith these rolls R R- receive rotary motion byreason of the frictional coutact of their race-pulleys with the underside of the upper half of the belt O( The spindles P receive rapidrotation for effecting the 'spinning of the rovings from a horizontalcylinder, T, journaled in the main frame A and receiving rotation from apulley, a', on the main shaft, acting through the medium of an endlessbelt, V, and a pulley, a2, on the shaft of the said cylinder.

IOO

X is a spool, from which is unwound the rovings by means of a drum, X2,on which the same impinges, which drum is on the shaft e of theintermediate gear-wheel, e, that derives its rotation from thespur-wheel a on the main shaft A, acting through the medium of themaster spur-wheel b, pinion c, and large spurwheel C'2 above described.The-j ournal of each end of spool X may bear upon a bracket, X', asshown in Figs. 1 and 2.

Az is the horizontal vertically-movable ringrail supporting the rings Band their travelers C', and A3 is the rail on which the spindles P arestepped. The cam B gives the ring-rail a slow steady upward motion untilit reaches the terminus of its upward stroke,wl1en t-his rail speedilydescends to a point--say one inchbelow the bobbin D2. The motion of thiscam is communicated to the ring-rail A2 by means of the curved rider Fl,projecting from one of the levers F, (the free end of which rider bearson the convex surface of the cam, as indicated in Fig. 2,) levers F2 F2,and vibrating arms Gr7 G7, which latter are connected by pivots andslots to vertical reciprocating staffs G2 G2, that pass freely throughthe step-rail A3' and are rigidly secured to the ring-rail A2. Thering-rail has a subsidiary motion given to it by the cam B3, the shaft Bof which has its bearing on the upper free end of the left-handvibrating lever F2 and vibrates coneentrieally with the axis of theshaft H. This cam B3 acts on the hook end of a rider, B7, adj ustablysecured to a horizontal rod, B8, to which the right-hand lever or leversF2 are suitably pivoted. The forward end of the rider BT is providedwith a longitudinal aperture for the ret ception of the horizontalY rodB57, andthis apertnred 'portion is provided transversely with one ormore threaded perforations for the passage of screws or bolts which adjustably secure the said rod to the rider. This mechanism B3 issubstantially similar in construction tothe mechanism B so far as thecam and rider are concerned; but the cam B3 is adapted to make, say,from fifty to seventy five revolutions while cam B makes but onerevolution, and cam B3 is driven by bevel-gears Hi41 H, whereas cam B isdriven by worm A4 and gear K, thereby `in a simple manner obtaining theproper rates of speed of the said two cams. In practice the cam B3 has athrow of from one to one and a half inch. The bevel-gear H5 H4 and shaftI are applied on the left-hand lever F2 and vibrate with it the beveledgears 2 3, maintaining a perfect mesh at all points of the vibrationwith the bevel-gear 2 3. The cam B gives the build and outline to acomplete cop, while the cam gives the rapid motion which forms the noseof the cops.

The travelers C' deliver the yarn on the bobbin as fast as it is paidout from the drawingrolls, and the drawing-rolls B B deliver the yarncompletely drawn and partiallytwisted over the notched guide-rail W tothe spindles P, which give the yarnits complement of twist.

By reference to Figs. 1 and 5, it will be observed that the race-belt Omoves in the direction of the arrows. This belt has a speed equal to thedesired feed ofthe rovings to the spindles, and the action of this belton the latter is as follows: As above described, the beltV O passes overand turns the race-pulleys R It on said roller-journals. Theseraee-pulleys being of the f same diameter as their rolls, itfollows'that the same rotary speed is given to the rolls that is givento the race-pulleys which drive them. The driving or pitman rod M givesthis drawing mechanism an alternate reciprocating motion, which directlyaffects the speed of said rolls, butnot the speed of the race-belt O.The speed of the drawing-rolls is affected as follows: First, when theserolls are receding from the spindles, the speed increases over thenormal movement of the race-belt to cover the distance passed over,(from points f to f,) and, second, in the downward or forward movementtoward the spindles t-liefliawing mechanism moves much faster than therace-belt and causes the rolls R B to receive rotary moti'on in adirection opposite to that which they have while receding.

The operation is as follows: The rovings pass out from the feed-rolls EE to the drawing-rolls R R, which ,must have a greater speed than thatof the rolls E E, and are thereby caused to draw the rovings to anyattenuated degree desired; but it is necessary that a certain per eentumof twistbe present at the place of drawing, which place is between thefeedrolls and the drawing-rolls, and the bodilyreciprocating movementsof these latter rolls allow the twist necessary for the drawing of evenyarn to pass up to the said place of drawing. As the drawing mechanismmoves forward, the drawing-rolls run downward upon the yarn between theguide-rail V and the feed-rolls E E, while the spindles are eonstantlygiving the yarn its finishing twist. After this twist is passed over bythe drawing-rolls in their forward motion these rolls IOO IIO

recede again, during which movement the y the drawing-rolls per minute.

Having described this invention, what l claim is- 1.
